Structure E is the:

• A. Zygomatic arch
• B. Foramen magnum
• C. Bony nasal septum (perpendicular plate of ethmoid and vomer)
• D. Body of maxilla (contains the maxillary sinuses)

Answer: (A)

The structure is the zygomatic arch—the curved bony bridge that forms the prominence of the cheek and connects the zygomatic bone to the temporal bone. It appears as a distinct arch along the side of the face on skull views. The other structures don’t resemble a lateral cheek arch: the foramen magnum lies at the base of the skull, the nasal septum sits in the midline of the nasal cavity, and the body of the maxilla is the upper jaw housing the maxillary sinuses.
